FAQs about noise
Environmental noise is 'unwanted sound' arising from all areas of human activity such as noise from transport, industrial and recreational activities. Excessive noise can:
- seriously harm human health, including mental health
- interfere with people’s daily activities at school, at work, at home & during leisure time
- disrupt sleep, cause cardiovascular and psychophysiological effects
- lower performance, lead to annoyance responses and changes in social behaviour

What is the role of the various competent authorities in relation to Dublin Airport?
Dublin Airport Authority (DAA)
The DAA manages aircraft noise at Dublin Airport and operates the WebTrak Flight Monitoring System, which allows the public to track flights, and to submit noise complaints. Complaints are investigated by the DAA Noise and Flight Track Analyst to determine whether an aircraft has breached the environmental noise corridor.
Air Nav Ireland provides air traffic control services in Ireland and manages the routes aircraft follow when arriving at and departing from Dublin Airport. It works with the DAA to review aircraft movements and minimise the environmental impacts of aviation, including noise.
Airport Noise Competent Authority (ANCA)
ANCA is responsible for assessing aircraft noise at Dublin Airport in line with EU and Irish legislation. It monitors compliance with noise mitigation measures and operating restrictions and applies the International Civil Aviation Organization (ICAO) balanced approach to aircraft noise management. Aircraft noise complaints should continue to be made to the DAA.
Fingal County Council is responsible for airport related planning matters, including enforcement of planning conditions. It also prepares the Dublin Airport Noise Action Plan (NAP) under the Environmental Noise Regulations, including public consultation on draft plans.
An Coimisiún Pleanála (formerly An Bórd Pleanála)
An Coimisiún Pleanála granted planning permission for the North Runway in 2007, subject to conditions including limits on nighttime use. Changes to these conditions were assessed by ANCA, approved by Fingal County Council in 2022, and where then appealed to An Coimisiún Pleanála. A government decision on whether to end the Dublin Airport passenger cap (32 million) is still under discussion.
Environmental Protection Agency (EPA)
The EPA oversees implementation of the Environmental Noise Regulations and provides guidance on noise mapping and Noise Action Plans for major transport sources. It reviews and publishes noise maps and annual progress reports, but its legislative remit does not include the enforcement of airport noise controls or other types of traffic noise. The EPA website provides guidance and links to the relevant authorities for addressing these noise complaints.

How would a road traffic noise complaint be investigated?
Road traffic noise complaints are mainly handled by Transport Infrastructure Ireland (TII) and local authorities. TII manages motorways and national roads, while local authorities are responsible for regional, public, and local roads. Each has different roles under the Environmental Noise Regulations.
When you contact your local authority, they will record the complaint and decide whether it should be addressed by the local authority, TII, or both. In some cases, environmental sections handle these noise complaints, while roads sections might also be involved in dealing with traffic-related noise issues.
If a noise problem area is identified as a Priority Important Area (PIA) in the local authority Noise Action Plan, the relevant local authority would be responsible for addressing it. Noise Action Plans should be available on the local authority website. Local authorities are legally obliged to develop cost-effective noise reduction measures and may work with other bodies, such as TII, where necessary on more complex issues around mitigation of environmental noise.

If I have a complaint about road traffic noise, who do I report it too?
In the first instance, you should contact your local authority. The Department of Climate, Energy and the Environment (DCEE) provide contact details for all local authorities on the gov.ie website. The local authority can advise whether a road traffic noise complaint falls within their responsibility.
If the issue relates to a national road or motorway, Transport Infrastructure Ireland (TII), which manages this network, may be able to advise on any planned works or noise monitoring data. Contact details and noise maps are available on the TII website.
TII is also responsible for preparing strategic noise maps for major national roads carrying more than 3 million vehicles per year and for light rail lines (Luas).

What is Low Frequency Noise (LFN) nuisance?
A small proportion of people are disturbed by low frequency sound, which is typically described as something like a low rumble. For those people who are affected, they can be severely distressed. Sometimes the complaint can be traced to a sound source, typically an industrial site, or an adjoining property. If the source can be found, then there is a chance the noise can be controlled.

What can I do about noise arising from public events?
Any event, such as a concert or festival, would normally require planning permission. However, in some cases, a particular venue may have prior approval to stage a set number of concerts/events per annum. The appropriate local authority (city or county council) should be contacted in relation to any noise complaints for these planned events.
